Twin brothers Michel and Ronald Mulder of The Netherlands both earned medals in the men's 500 meters speed skating event - an incredibly rare occurrence in the Olympics.
Michel, 27, who was born 10 minutes after his brother, won gold, and Ronald took home the bronze.
For a brief moment, Jan Smeekens of The Netherlands thought he had won gold after he crossed the finish line, however the clock adjusted his official time giving Michel Mulder the gold by 1/100th of a second.
Defending Olympic champion Mo Tae-bum of South Korea was fourth.
The Mulder twins aren't the first siblings to compete against each other in Sochi and win.
Justine and Chloe Dufour-Lapointe of Canada, swept the top two spots in the women's moguls competition over the weekend.
However, twins medaling in the same event at the Olympics is especially rare.
In 1984, twins Phil and Steve Mahre won gold and silver, respectively, in the men's slalom in Sarajevo.
